It provides a generic set of tools for initializing a synthetic
population with each individual in specific disease states, and
making transitions between those disease states according to the rates
calculated on each timestep. The new version 1.0.0 has C++ code
integration to make the functions run faster. It has also a higher level
function to actually run the transitions for the number of timesteps
that users specify. Additional functions will follow for changing
attributes on demographic, health belief and movement.
